The problem I have with the traxxis is that it doesn't run on 12v so you have to manually power it on and maybe change the batteries once every 5 years (kidding really)
The same is true for the BBQ sensor and IRRC neither are back lit.
The original one is made by SURE. They also make plug and play thermometers that are 12v and back lit. Also they're $12 shipped.

They also have a lot of fun features, but most importantly LOOK GOOD (I'm vain - shoot me) and power up when you turn on your 12v system. Unfortunately, they only go up to 120c. That's way below the currie temperature of magnets, but what is the real max temp we should be setting for our motors?
OTOH, the original temp sensor I posted is scalable.... so you could literally monitor any temp you want by using the appropriate thermocouple and programing via usb the display to what ever you want.
My sure thermometer should be here tomorrow(after almost a month
), so I'll posts some pics once it's all setup to monitor my ping pack this summer.
